Definitions

  • the present invention refers to a plant for continuously manufacturing a foam layer having undefined length; the layer is obtained by advancing a plurality of laying planes, on which foam has been deposited, along a predetermined direction.
  • the layer is divided into a plurality of rest articles by means of successive cross cuts.
  • Each laying plane is provided with a plurality of protuberances capable of forming cells into the layer.
  • the continuous plant is suitable for manufacturing foam mattresses provided with cells.
  • EP 1025 972 Al refers to a device for the manufacture of a continuous foam layer.
  • the device comprises a chain having bearing plates rigidly mounted onto the links and provided for supporting the slats of the conveyor.
  • the slats comprises solid pins.
  • the plates and the solid pins are made of aluminium.
  • the chain structure has to be made of a stronger and more wear resistant material in particular of stainless steel. Due to the different thermal expansion coefficient of aluminium and steel, problem arise in the above described device.These problems have been solved by mounting the slats in a slidable manner onto the chain structure.
  • the bearing plate with slots and the slats with pegs extending through the slots in such a manner that the slats are fixed to the bearing plate but still can slide relative thereto over a distance equal to the length of the slots.
  • the length of the slots may be on the order of about 4 to 5 cm and the slats may have a width of 30 cm.
  • European Patent EP0 955 144 discloses a continuous plant for continuously manufacturing latex foam articles.
  • the mattress comprises a plurality of portions adapted to support the different body parts of the user.
  • a first portion is for head support
  • a second portion is for shoulders and back support
  • a third portion is for the loin region
  • a fourth portion is for the legs
  • a fifth portion is for the feet.
  • Each portion has a distinctive support capacity value, usually different, sometimes slightly different from the other portions.
  • one of the comfort parameters is the support capacity of a foam mattress which depends on many factors such as sinking strength, compression strength and resilience.
  • the support capacity is the degree of reaction exerted by the mattress resilient material when it is subjected to the weight of the human body.
  • the support capacity can be determined in many ways, for example by the reaction, measured in Newton, of a foam block when compressed at 40% of its rated thickness.
  • the customer may therefore require the manufacturer to customize the support capacity of different portions of the mattress and the manufacturer should follow and meet the customer requirements - often hospitals or great dealers of furniture and rest articles.
  • a predetermined cell distribution suitable for example, for a customer requiring the maximum support capacity in the head supporting area might be unsuitable for a customer requiring lower support capacity in the same area, therefore the mattress manufacturer has to vary both the distribution and the size of the protuberances needed to mould the head support portion.
  • European Patent EP 0 955 144 discloses a continuous plant for manufacturing latex foam mattresses having differentiated support capacity areas.
  • Such plant comprises a plurality of carriages moving along an annular pattern defined by a first upper branch between a foam injection station and a second mattress drawing station and by a lower branch for returning the carriages without foam to the injection station.
  • the total length of the plant may range from 25 to 50 metres and even more.
  • the carriages may range from 20 to 100 cm along the plant longitudinal size and 220 cm crosswise.
  • Each carriage has an upper base, called laying plane, from which a plurality of overhanging protuberances, arranged according to a pattern and shape corresponding to the cell profile of the mattress, project.
  • the distribution of the protuberances on the laying plane is such that it provides amounts of foam having specific support capacities.
  • the handling of the lower branch carriages is performed by three conveyor belts each one with self speed.
  • the intermediate conveyor belt is arranged on transversally moving means in such a way that it is possible first to draw out one or more carriages from the plant in order to modify their size, then replace the modified carriages along the lower branch without interrupting the manufacturing cycle.
  • the known solution would offer the opportunity of adjusting the plant to a new production cycle for a different product.
  • This solution may be adopted also to vary the protuberance shape, dimensions and/or heights of each carriage.
  • each protuberance comprises a thread necessary to engage with a corresponding female thread on the laying plane.
  • each carriage may comprise a grid consisting of multiple horizontal and vertical rows of protuberances, in some cases over 350 protuberances, therefore any change in size and/or shape of a single carriage would require elaborate and very long procedures.
  • the problem of changing the protuberance distribution in order to meet the requirements of a new customer increases in that the known plant may comprise more than 40 carriages, each of which requires the abovementioned operations to vary the protuberance distribution.
  • the carriages feeding speed and the step of laying the latex foam among the continuously moving protuberances are processing parameters particularly relevant for the result to be achieved.
  • the distribution of the continuously moving protuberances is a parameter affecting the good result of the end product.
  • the latex foam injected while the carriages are moving might not flow along the protuberance sides and might not reach the carriage bottom thus resulting in an end product whose structure will not be complete in all the portions meant in the beginning.
  • the problem to be solved by the invention is to provide a plant for manufacturing a foam layer of indefinite length to be divided in a plurality of rest articles, where the distribution of protuberances can easily be changed so as to conform the support capacity of different article portions to the requirements of individuals users.
  • the plant 1 of figure 1 is adapted to manufacture a continuous latex foam layer 2 ( fig. 2 ) of unlimited length upwardly and downwardly defined by two faces 3, 4 respectively, at least the lower face being crossed by cells 5.
  • the continuous layer 2 is then subjected to cross cuts transversal to its length; these are made at a predetermined distance in order to obtain single mattresses 6 ( fig. 3 ) defined by a width W lengthwise to layer 2 and by a length L according to the cutting direction.
  • the plant 1 comprises a plurality of side by side placed laying planes 7, continuously fed in the longitudinal direction F between a latex foam laying station 8 and a foam layer drawing station 10 provided with a pair of rolls 11 each rotating in opposing direction with the layer running in between.
  • the station 8 is provided with a laying device 9.
  • a latex foam gelation and vulcanizing device 12 Between stations 8 and 10 is a latex foam gelation and vulcanizing device 12.
  • the tables are made of many kinds of metals, preferably aluminium, with thicknesses ranging from 2 to 10 mm.
  • Each table 13 is provided with a plurality of upwardly cantilevered protuberances 14, preferably made of aluminium.
  • the protuberances may be tapered and ended in a point or for instance they may be cylinder shaped with a circular connection on their top, or cylinder shaped at their base and tapered toward their top or anyway, of any shape to mould cells in the latex foam.
  • FIG. 4 For a better understanding of the novel feature of the plant a fragmentary perspective view of Fig. 4 is used, wherein for sake of simplicity, only a table 13 is represented with protuberances 14 already arranged according to a predetermined distribution.
  • the term “distribution” means the relative distance between the axes and the protuberance walls as well as their number per square decimeter, that is the data which allows to define a specific grid comprising horizontal and vertical rows directed along the main dimensions of each table.
  • the several tables 13 can be slidably inserted and drawn on and from the laying plane 7 respectively.
  • each table 13 is slidably inserted and drawn along the plant longitudinal direction F; each table 13 has a length "I” along the plant longitudinal direction F, a width “l a “ transversal to "I” and sides "f".
  • the arrangement of all the tables 13 provided with protuberances 14 on each laying plane 7 covers an area corresponding to the area of a mattress 6 ( fig. 3 ).
  • all tables 13 make up an area having a total length "I”, corresponding to the width "W” of the mattress 6, and a width "nI a " which corresponds to length "L” of the mattress, wherein "n” is an integer between 4 and 9, preferably between 5 and 7.
  • the width of table 7,corresponding to the mattress length may be 220 cm.
  • a further characteristic of the plant consists of guiding means which allow tables 13 on the laying plane 7 to be slidably fitted along the longitudinal plant direction F.
  • Such guiding means comprise members which longitudinally contact sides "f" and cover the edges of each table along direction "I".
  • such guiding means consists of a pair of T-shaped beams 15 ( figure 5 ) with each table 13 slidably fitted in between.
  • tables 13 contact the leg of the T shape while the head of the T-shape is part of the laying bed of the latex layer.
  • the guiding means15 can consist of pairs of countersunk-head beams, each with a table 13 in between having corresponding countersinks in its upper portion. Therefore, with this arrangement, the beam heads and the upper end portion of the tables are aligned thus making up a continuous laying bed for the latex.
  • each has a distribution of the protuberances 14 which may differ from the distribution of the juxtaposed tables in order to create afterwards areas having different support capacity as to the various body parts of the user.
  • tables 13 are adapted to define five areas differentiated as for support capacity for a user's body. In other embodiments, these areas may be seven.
  • Tables a, b, c, d, e together with protuberances 14 are adapted to form supporting areas for the following parts of the body:
  • the plant allows to automatically adapt the moulding means of the plant, that is the protuberances 14, designed to form the different supporting areas of the body.
  • the protuberance distribution of table "c" is such that it creates the maximum support capacity, the protuberance distribution of tables “a", “e” creates support capacity values slightly lower and the protuberance distribution of the other tables creates even smaller values.
  • the manufacturing process of the second cycle requires maximum support capacity values for the shoulders while for the head and feet it requires support capacity values lower than the example described before.
  • the novel characteristic allows the arrangement of a series of tables 13 provided with protuberances 14 having a different distribution from the distribution adopted for the first cycle.
  • the plant takes advantage of further characteristics which contribute to correctly form a plurality of rest articles having different support capacity without significantly departing from the manufacturing parameters even though tables 7 have been replaced, as previously described.
  • the centre distance value "x" is 40 mm in the protuberance row parallel to length "I" of each table and 43 mm in the perpendicular row.
  • protuberance distributions are described with reference to the embodiment in figure 7 , wherein along three horizontal rows the protuberance distributions relative to three tables interchangeable with one another, for example during three different manufacturing cycles, are shown.
  • a first plurality of tables "a” provides the following characteristics: Diameter of two consecutive protuberances 16 mm.
  • a second plurality of tables "a" in replacement of the first plurality provides centre distance values "x" unchanged.
  • the second plurality of tables "a" has a lower distance between consecutive protuberances, therefore the amount of gaps in the user's head supporting portion will be greater than in the first plurality of tables.
  • a third plurality of tables "a" interchangeable with the first provides a centre distance "x" unchanged and: Diameter between two consecutive protuberances 24 and 16 mm respectively. Distance “t 3 " between the sides of the same protuberances 20 mm.
  • the table replacement in the two examples mentioned before allows the starting mixture density to be kept unchanged, having density values ranging between 50-70 g/l while the apparent density may range from 30 to 60.
  • the laying planes 7 of the plant 1 are represented by carriages on the upper base of which the tables 13 provided with protuberances 14 are slidably fitted.
  • a supporting block 18 ( fig. 9 ) at the base of each carriage supports some rollers 19 whose spindles engage the pulleys drive means 20.
  • the carriages 7 are pushed by the driving wheel to contact each other along the upper active branch wherein the tables 13 receive the latex foam, injected by means of device 9, among the protuberances 14.
  • the carriages of the lower branch can be fewer than the carriages in the upper branch and with this arrangement they move by means of moving means, such as conveyors and alike, independent from the driving pulley, at a speed higher than the upper branch.
  • the above mentioned moving characteristics of the carriages 7 and their speed in the lower branch allow the use of an apparatus 24 on the upper surface of which various tables 13 provided with protuberances 14, adapted to replace the tables placed on the carriages, can be arranged.
  • the apparatus 24 can be brought closer between the two conveyors of the lower branch, then drawing the tables 13 on the laying planes and replacing them with tables 13 lying on the apparatus 24.
  • the upper portion of the plant comprises a plurality of plates 25, each provided with a plurality of protuberances 26 adapted to form the upper cells.
  • Plates 25 move along an annular path wherein the lower section is the active part passing through the gelation and vulcanizing device 12.
